Letters Patent No. 99,826, lated February 15, 1870.

The Schedule referred to in these Letters Patent :arid making part ofthe same To all whom it may concern: l

Be it known that I, SAMUEL C. BRADLEY, of N ew Haven, in the county ofNew Haven, and State yof Connecticut, have invented a new Ilnprovenientin Joiners Clamp; and I do hereby declare the following, when taken inconnection with the accompanying drawing, and the letters of referencemarked Vthereon, to be a full, clear, and exact. description of' thesame, and which said drawings constitute part of this specilication, andrepresent in Figure 1, a side view,

Figure 2, a top view, the movable arm locked in i position, and innotches, may be set into such notch and firmly hold the. arm inposition.

A is the beam, constructed with a fixed arm, B, and upon the sides ofthe beam grooves a are formed. Over the beam an adjustable arm, C, isarranged, to slide freely on the beam, and into the outer end of the arma. binding screw, D, is set.

Ou the arm O a slide, d, is arranged, so as to be set into any one of'the grooves, as' in figs. l and 2, when the arm is adjusted, so as tobring the slide into p0- sition, that it may be set into one of thegrooves, and when so set, as in figs. -1 and 2, the arm is rmly held.

To adjust the arm, draw out the slideyas denoted in broken lines, iig.1, and as also shown in fig.'3, and movethe arm C to or from the fixedarm B to the desired position, and return the slide into' acorresponding notch.

By this construction, moved to any position, and the clamp set uponrthe`work without the necessity of running the screw to any great length outor in,'as in clamps oi" common construction. Y

I am aware that clamps have been constructed with adjustable arms, Itherefore do not wish to be understood as claiming such construction;but

I do claim- A clamp, composed of the beam A, constructed with the fixedarm B and grooves a, in combination with the adjustable arm C, havingthe slide al ar ranged thereonpand operating in the manner described.
